Celeriac 'Mars'

Apium graveolens var rapaceum

• Large, uniform 1.5-2kg, dense roots
• Upright plants
• Firm interiors
• Long storage

Large 1.5-2kg, uniform roots with big, healthy, upright plants. Interiors stay firm, even when roots are large. ‘Mars’ is a medium early celeriac with good bolt resistance. Holds well in the field. Upright plant results in less splash from rain and, hence, less soilborne Septoria blight as well as easier cultivation.

Celeriac can be used raw in salads, eaten as a cooked vegetable or used in soups and stews. Stores well.

Seed Raising, Growing and Harvest Information

TRANSPLANTING (recommended) - Start seeds 10–12 weeks before transplanting outdoors. Sow 6 seeds every 2.5cm, 3mm deep, in open flats, or plug trays. Keep soil moist and temperatures 21–24°C if possible. Seedlings emerge in 2–3 weeks and then temperature can be reduced to 16–21°C.

When seedlings have 2 true leaves, transplant to pots or soilblocks and continue to grow.

Transplant outdoors when weather is warm and settled 15-20cm apart in rows 60-90cm apart. Irrigate to keep soil moist.

NOTE - There is risk of plants bolting to seed if they are planted out when daytime temperatures are consistently below 13°C. This crop needs a consistent supply of moisture throughout the season for optimum flavor and yield.

NOTE: In rare instances, contact with the foliage can result in a severe rash. When working with this crop on hot, sunny days, we recommend wearing long sleeves and long pants, and washing any exposed skin surfaces as soon as possible after contact.
